The Indian Institute of Technology (IIT) Kharagpur has collaborated with the British Geological Survey (BGS) to turn Varanasi into a smart city. As part of the project, three dimensional geological modelling of the geology under Varanasi will be prepared to help improve the building of new transport and service infrastructure. The project includes application of geo-scientific methods like drilling, geological, geophysical, tectonics, hydrogeological and remote sensing. It would be the first major 3D subsurface urban study and planning of its kind in India, with the ultimate aim of developing methodologies and input of suburban geology for planning and hazard risk assessment. The purpose of the project is to develop the methodologies and approaches of urban geosciences and engineering of Varanasi as a pilot for other Indian cities.

Two times IPL champions Mumbai Indians (MI) reached a new milestone as they became the first team in history to win 100 T20 matches. The Mumbai outfit defeated Kolkata Knight Riders (KKR) at the Eden Gardens by 9 runs in their final match of the league stage of IPL 2017.

The 112-feet tall bust of ‘Adiyogi’ Lord Shiva at the Isha Yoga Foundation has been declared the world’s largest bust by the Guinness Book of World Records. The Guinness had announced this on its website. The bust at the Isha Yoga Foundation on the outskirts of Coimbatore, Tamil Nadu was unveiled by Prime Minister Narendra Modi on 24 February.

Let P's speed = x km/hr. Then, Q's speed = (7 - x) km/ hr.

So, 24/x + 24/(7 - x) = 14

x2 - 98x + 168 = 0

(x - 3)(x - 4) = 0 => x = 3 or 4.

Since, P is faster than Q,

so P's speed = 4 km/hr and Q's speed = 3 km/hr.

Let the number be x. Then,

3x2 - 4x = x + 50

3x2- 5x - 50 = 0

(3x + 10)(x - 5) = 0

x = 5

Let the speeds of the two trains be x m/sec and y m/sec respectively.

Then, length of the first train = 27 x meters, and

length of the second train = 17 y meters.

(27 x + 17 y) / (x + y) = 23

=> 27 x + 17 y = 23 x + 23 y

=> 4 x = 6 y

=> x/y = 3/2.

By hit and trail, we find that

47619 x 7 = 333333.

7) 333333 (47619
    333333
----------------
        0

And 476190476 x 7 = 3333333333 but smallest number is 47619.
